What I don't understand is what Obama thinks he has to gain from this. Clearly, Trump thinks he gains from his hate by agitating his base and getting media attention to reach for more haters to join him. And, for example, Obama presides over the horrendous nightmare of the destruction of Yemen, with thousands of cluster-bombed and conventionally-bombed civilians' blood on U.S. hands (not just because the weapons were knowingly sold by the U.S., but also because the U.S. provides to the Saudis direct targeting assistance in this campaign, and also helps enforce blockades that kill people, etc.), because it serves U.S. "interests." But surprise, indiscriminate banning of Muslims from visiting the U.S.--what U.S. purpose does this serve? Maybe it is part of the recognition that if more U.S. people actually meet and hear from Muslims visiting from beyond the U.S., then more understanding will grow within the U.S. of the heartlessness of the many U.S.-led or U.S.-backed wars that devalue Muslim lives, and more connections could be cultivated between peace-desiring people on both sides of the U.S. border. And developments like this could undermine U.S. war-business. More love and less hate, please!
